This document discusses four approaches to curriculum development: behavioral, managerial, systems, and humanistic. The behavioral approach focuses on specifying goals and objectives and arranging content and activities to meet those objectives, evaluating learning outcomes based on the goals. The managerial approach emphasizes the principal's role in setting policies, planning, and organizing curriculum implementation. The systems approach views all parts of the school as an interconnected system. The humanistic approach places the learner at the center and aims for their total development. Curriculum developers may draw from one or more of these approaches.
